# Common Issues

<details>

<summary><strong>Callouts not appearing</strong></summary>

Upgrade the latest search UI package and confirm callouts were displaying correctly in the **Merchandising Preview**.

</details>

<details>

<summary>Filters not appearing</summary>

Review front-end implementation and ensure filters are not being unmounted.

</details>

<details>

<summary>Searching by SKU is not working</summary>

Check that the relevance settings include the Product SKU field.

</details>

<details>

<summary>Pagination is slow when filter and sort are used on collection &#x26; search pages</summary>

Always a front-end implementation issue. Check the **Merchandising Preview** and confirm that preview is not experiencing the same issue. To resolve, front-end must optimise the page rendering
